Recently, i Used the o2 simulator (dual version) to slove the Code P0430(bank 2),it's the red harness one.I cut the wires before the connector and it is working great and the code never come back,but now I have a P0158 code,it says the oxygen sensor bank 2 also same harness. Does any body know do i need to replace a new oxygen sensor or i can use the o2 sim to connect with the sensor signal wire after the connector? cus i got a dual version.

Are you CALI spec with 4 O2 sensor plugs infront of the valve cover ? That code means your 02 sensor is sending TOO much voltage to the ECU. If you use both signal wires - one before and one after the connector on ONE 02 sensor this code WOULD pop up.

even if your secondary o2 is bad, the simulator is simulating the wires BEFORE the connector (EGI harness side)....so it shouldn't matter if your secondary o2s are bad or not

yeah..that's right the signal wire were cut already,i think maybe it's the o2 sim goes bad,i'll try to clear the code and let see will it come back!

is your LED blinking?

i would think if the simulator is bad, it would throw a low voltage code or no response code...its throwing a high voltage code, meaning something is producing those volts somewhere...

The LED is still blinking, but i drove 50 some miles after i clear the code from auto zone,no CEL yet!! i hope the code won't come back ,if not...i will get in trouble...
